Characteristics Value UnitsThe 30BQ040PbF surface-mount Schottky rectifier has been

designed for applications requiring low forward drop and smallfoot prints on PC boards. Typical applications are in disk drives,

switching power supplies, converters, free-wheeling diodes,

battery charging, and reverse battery protection.

Small foot print, surface mountable

Very low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long termreliability
